UNITED STATES PATENT BABY BOTTLE CONTAINER I James 0. Austin, Bluefield,Va.

Application April 25, 1947, Serial N0. 743,967

' 1 Claim.

The present invention relates to an improved container which isexpressly, but not necessarily, adapted to hold and protect a nursingbottle for use by an infant.

The principal object of the invention is to provide simple andinexpensive nursing bottle holder or container wherein same is made upof coacting body and cover sections and the sections, in turn, beingmade up of inner and outer complemental parts, certain parts beingspaced apart to provide dead air spaces which, in turn, function topermit the container to serve somewhat in the capacity of a so-calledvacuum bottle.

Another object of the invention is to structurally, functionally, andotherwise improve upon holders and containers such as have been proposedfor use by others, this by providing a structure which is unusuallyeconomical, practical and such that, in use, it serves to amply shieldand protect the bottle, keeping the contents of the bottle insatisfactory condition for safe use over periods of several hours time.

Other objects and advantages will become more readily apparent from thefollowing description of the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate likeparts throughout the views:

Figure 1 is a side elevational view of a nursing bottle container orholder constructed in accordance with the principles of the presentinvention.

Figure 2 is an enlarged sectional view of the same.

Figure 3 is a cross-sectional view on the plane of the line 33 of Figure2, looking in the direction of the arrows.

Referring now to the drawings by distinguishing reference numerals, itwill be seen that the container, as an improved unitary device, isdenoted by the numeral 5 and that same is made up of complemental bodyand cap-like closure sections 6 and 1 respectively. The body sectionincludes a cylindrical shell which is open at its top and which isdenoted by the numeral 8 and screw-threaded at its upper end, as at 9,and is further internally provided with annular spacing ribs I0, I I andadditional spacing elements I2. This shell serves to pocket andadequately maintain in place an inner shell or lining I3 which ismaintained in spaced relation to provide a dead-air chamber or space, asat I4, The inner shell .is provided with internal ribs I5 and spacingelements I6 which serve to properly cushion and support the nursingbottle I'l, this,

as shown in Figure 2. The upper end-portion of the lining or shell issuch that it protrudes above the threaded portion 9 of the outer shell.In addition, the outer surface of the inner shell is provided withsuitable detents I8 which have removably snap relationship with theadjacent annular rib II. The fact that the parts 8 and I3 are preferablymadefrom slightly elasticmaterial enables the inner part o'rshell" toyield to provide the snap retention result just described. It followsthat the inner shell can be removed from the outer shell, and both partsmay be washed and reassembled, whereby to insure reasonable sanitationat all times.

The cover means! is also of sectional construction and comprises a mainouter cap I9 which is provided with a spacing internal rib 20 and whichis screw-threaded as at 2|, to engage the aforementioned threads 9. Asuitable spacing button or lug 22iis provided between the interior ofthe outer cap and the crown portion of the inner removable cap 23. Thus,the two caps are spaced apart to provide a dead-air space as at 24, andthe inner cap is provided with detents 25 which engage the retaining andassembling rib 20.

It follows that both parts 6 and I of the container are made up ofsections and the sections are connected releasably one with the otherand serve to define dead-air spaces, which, in turn, produce the desiredvacuum bottle effect.

I have found it expedient and practicable to construct the body andclosure parts from coacting sections, providing ribs between thesections, in order to define the so-called vacuum or deadair spaces. Byemploying plastic or equivalent stock and providing the inner memberswith simple detents, and arranging'the detents to releasably engage theinternal ribs, the sections which go to make up the respective parts arereadily separable for assembling, repair and washing purposes.

It is submitted that even though the device is of unusual simplicity, itnevertheless provides a practical vacuum container for nursing bottles,thus keeping the bottle clean and sanitary and also preserving thecontents of the bottle for practical utility by the owner.

Reference being had again to certain structural details, it will benoted that the upper end of the liner or shell I3 projects slightlyabove the corre spondingly externally-threaded upper end of outer shell8 and has a slightly rounded terminal edge. In fact, this extendingportion of the liner projects up into the outer cap and the inner caphel a ina being shorter than the outer one has its lower edge formedwith a groove. It follows that the two parts l3 and 23m together intongue and groove fashion as denoted at 23a.

A careful consideration of the foregoing description in conjunction withthe invention as illustrated in the drawings will enable the reader toobtain a clear understanding and impression of thealleged features ofmerit and novelty sufficient n erim-thercpes i ni vther rv ie tion ashereinafter claimed.
